SOLVED: Playback fail the first time

[Squid]

How, exactly, did you move the files?  Because if you removed the old path from the library BEFORE scanning in the files at the new location, Jellyfin can bug out.

Relocate files
Scan library to pickup the new location
Remove old folder from library

backed up jf container
formated the server
made new file structure on host
put file in the new struct
attached the new path in to jf container
rescanned library (with replace stuff) several times.
